Abstract

Die Erfindung bezieht sich auf einen Ultraschall-Strömungssensor zur Erfassung der Durchflussrate eines in einem Strömungskanal (1, 3) strömenden Mediums (2). Quer zur Strömungsrichtung (30) des zu strömenden Mediums (2) werden Schallsignale (24) eingekoppelt. Einer Wand (4) des Strömungskanals (1, 3) ist ein Ultraschall-Wandlerarray (20) zugeordnet. Dieses umfasst sowohl ein Sendeteil (21) für das emittierte Schallsignal (24) als auch ein Empfangsteil (22) für reflektierte Schallsignale (25, 26).The invention relates to an ultrasonic flow sensor for detecting the flow rate of a medium (2) flowing in a flow channel (1, 3). Transverse to the flow direction (30) of the medium to be flowed (2) sound signals (24) are coupled. A wall (4) of the flow channel (1, 3) is associated with an ultrasonic transducer array (20). This comprises both a transmitting part (21) for the emitted sound signal (24) and a receiving part (22) for reflected sound signals (25, 26).
